SEEDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 620,370, dated February28, 1899. Application filed December 24,1893. Serial No. 706,207. (Nomodel.)

To all whom it may concern:

Be it known that I, WALTER W. SCHULTZ, residingat Richmond, in thecounty of Wayne and State of Indiana, have invented certain new anduseful Improvements in Seeding- Machines, of which the following is aspecifi cation.

My invention relates to improvements in seeding-machines employing apair of rotary disks upon inclined axes.

The object of my invention is to provide novel means of constructing thesupporting parts of said disks and their drag-bars, so as to cheapen thecost of manufacture and at the same time make the said parts readilyrenewable, improving the strength and durability of said structure.

The features of my invention will be more fully set forth in thedescription of the accompanying drawings, making a part of thisspecification, in which- Figure 1 is a side elevation of my improvementattached to the drag-bar of a grain-drill. I

Fig. 2 is a sectional elevation of Fig. 1 with one of the disks andsection of drag-bar removed. Fig. 3 is a section of drag-bar attached toits hanger-bracket. Fig. 4is a central vertical section on line X X,Fig. 1. .Fig.

I 5 is a perspective view of the duplex stubaxle.

' A A represent the two sections of the dragbar, the forward ends ofwhich are hinged to the ordinary grain-drill frame in the usual manner.

B B represent hanger-brackets of the form shown.

C represents'the seed-tube. Said tube is provided with lugs c onopposite sides of the front and top portion thereof. These lugs engagein recesses 1), formed at the top end of the hanger-brackets. It will beobserved that the hanger-brackets are attached to the dragbars near thecentral portion thereof and that they curve upward and project above thedisks, so as to form a proper support for the seed tube, which dependsdownward between the disks, as shown in Fig. 4.. These hangerbracketslikewise extend downward below the drag-bars for suflicient distance toform hanger-supports for the duplex axle D. The

ends of this axle-piece are preferably pro vided with polygonal sidedprojections d, which seat and engage in similar-shaped orifices e of thehanger-brackets B B. A shoulder is formed upon said axle-piece at eachend thereof. The face of said shoulders are inclined invertical line andparallel with the plane of the revolution of the respective disks. Theinner faces of the hangers opposite the axles are inclined in a similarplane with that of the shoulder thereon, and they arepreferablyrecessed, so as to receive the ends of the respective axles. I

The duplex axle is provided with a central dividing-flange g to form abearing-support for the disk-journals.

D represents an upwardly-projectin g stem.

It represents an oil-passage reaching from the top of the stem downwardto the hub and terminates in branch conduits forming exitorifices e' 71under the guards j of the respective hubs.

H represents a pivoted cap for covering the oil-passage.

I I represent disks provided with sleeve- 75 hubs J, secured to thedisks. These hubs journal upon their respective stub axles. The axlesare shown tapering, which is the preferred form of construction.

K represents a coupling-rod or tie-bolt for rigidly securing the saidstub-axle firmly withv in its seats in the respective hanger-arms B B.

L represents a spacing-block separating the drag-bars and provided withan elongated mortise forming a seat in which is pivoted loosely thefender M, which is allowed to move freely back and forth the distanceshown by dotted lines, Fig. 2. The edges of the shanks of the fenderserve as stops to limit the said movements. Normally this fender hangsin the position shown in Fig. 1. It is readily moved forward forclearing out clods'or other substances,whieh are sometimes accidentallycaught in between said disks.

The seed-tube Ois provided, as shown, with 5 a rearwardly-extended arm10, to which is attached the ordinary covering-chain. When it is desiredto employ covering-wheels, they are connected to the pivots 'n on thehangerbrackets B B. I

It will be observed in this construction that the seed-tube, duplexstub-axle, and hangers,

which form the supports for the seed-tube and disks, are made ofseparate pieces and are readilydetachable for renewal. The stubaxleswear out much more rapidly than the other parts of the seeding device.They are readily renewed and at small cost. By the construction hereinshown I am enabled to obtain a very strong and rigid structure at acomparatively small expenditure of metal.

By constructing the duplex stub-axle and the hanger-brackets in the formherein shown I am enabled to use a straight tie-rod, thereby equalizingthe strain centrally around the axis of said bolt, and at the same timethe rotary frictional strain is sustained by the arms of thehanger-brackets, which are braced and supported by the drag-barsattached centrally thereto, making the said several parts lighter,stronger, and more durable than the means hitherto usually employed. I

IIaving described my invention, what I claim is 1. In a seeding-machine,the combination with parallel drag-bars, hanger-brackets secured to eachof said drag-bars and projecting above said drag-bars and forming asupport for the seed-tube and with downwardlydepending arms formingaxial supports for a pair of seed-disks journaled within said arms,substantially as specified.

2. In a seeding-machine, the combination with parallel drag-bars,hanger-brackets secured to each of said drag-bars and projecting abovesaid drag-bars and forming a support for the seed-tube and withdownwardlydepending arms forming axial supports for a pair ofseed'disks, substantially as specified.

3. In combination with parallel drag-bars,

, depending hanger-brackets connected to each of said bars respectivelyand depending downwardly therefrom and a duplex stubaxle the ends ofwhich are seated in said hanger-arms and detachably connected thereto,substantially as specified.

4. In combination with parallel drag-bars, depending han ger-bracketsconnected to each of said bars respectively and depending downwardlytherefrom and a duplex stub-axle the ends of which are seated in saidhanger-arms and detachably connected thereto and the axes of said stubsare respectively inclined to of parallel drag-bars, hanger-bracketscon-- nected thereto, a pair of revolving disks having theirjournal-supports detachably connected to said brackets, a seed-tubedetachably connect-ed between the upper end of said hanger-brackets anddepending downward between the plane of rotation of the inclined disks,substantially as specified.

7. In combination with parallel drag-bars, hanger-brackets connected toeach of said drag-bars, a duplex stub-axle having its ends seated insaid brackets and detachably connected thereto, substantiallyasspecified.

8. In a seeding-machine, aduplex stub-axle provided with acentral flangeforming a line of division between the respective axes, the

ends of which are adapted to be detachably secured to hanger-supportsand an oil-stem having divided discharge-orifices rigidly connected tosaid division-flange, substantially as specified.

9. In a seeding-machine the combination with parallel drag bars havingsuitable hanger-bearings supporting two inclined revolving disks, thespacing-block L located between said dra -bars and provided with anelongated mortise and the fender M provided with a shank loosely pivotedin the recess of the spacing-block, the edges of the shank serving asstops to limit the movement in each direction, substantially asspecified.

In testimony whereof I have hereunto set my hand.
